Abstract
PURPOSE: To enhance the operatability in turning by one-side caterpillar drive by a method wherein left and right caterpillars capable of being driven and stopped independently are provided with idle rollers, and the stop-side caterpiller is driven temporarily when the difference in speed between the drive-side caterpiller and the idle roller is not less than a preset value at the time of the turning by one-side caterpiller drive.
CONSTITUTION: The idle rollers 13 capable of rolling against the ground as the vehicle travels are provided closely to the left and right caterpillars 1, and speed difference detectors 14 for detecting the difference in speed between the caterpillar 1 and the roller 13 are also provided. At the time of the turning by one-side caterpillar drive, when the difference in speed between the drive-side caterpillar 1 and the roller 13 reaches or exceeds the preset value, the stop-side caterpillar 1 is driven temporarily by operating a timer in a controlling mechanism 16, on the basis of the information supplied from a turning discriminator 15 and the speed difference detector 14. Accordingly, the operatability in the turning byh one-side caterpillar drive can be enhanced.
